Description

Technical Field

[0001] The utility model relates to the field of disc-type separators, in particular to a lubrication-assisting structure of a disc-type separator. Background Art

[0002] The disc separator is a type of sedimentation centrifuge, which is used to separate materials that are difficult to separate, such as suspensions composed of viscous liquids and fine solid particles or emulsions composed of liquids with similar densities. The main working principle of the disc separator: The drum is at the upper end of the vertical shaft and is driven by a motor through a transmission device to rotate at high speed. There is a small gap between the discs. The suspension or emulsion is added to the drum through the feed pipe located in the center of the drum. When the suspension or emulsion flows through the gap between the discs, the solid particles or droplets settle on the discs under the action of centrifugal force to form sediment or liquid layer. The sediment slides along the surface of the disc and detaches from the disc and accumulates at the largest diameter part of the drum. The separated liquid is discharged from the drum from the liquid outlet.

[0003] After the disc separator is started, the transmission shaft is located in the lubricating oil chamber at the bottom and can be effectively lubricated, but the vertical shaft is located at the top and the lubricating oil cannot reach it, resulting in the vertical shaft and bearings not being well lubricated. The longer the machine is started, the higher the temperature will be, causing the bearings and shafts to sinter, causing wear and even damage to the vertical shaft. Utility Model Content

[0004] The utility model aims to provide a lubrication aid structure for a disc type separator, so as to solve the problem in the prior art that the vertical shaft and the bearing of the disc type separator are located at a high position and the lubricating oil is difficult to lubricate the vertical shaft and the bearing.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a lubrication auxiliary structure of a disc separator, including a transmission shaft located in a transmission box of the disc separator, the transmission box is filled with lubricating oil, the transmission shaft is connected to an active part located in the transmission box, the bottom end of the vertical shaft of the disc separator is coaxially connected to a driven part, the driven part extends into the transmission box and transmits power to the active part, the transmission shaft is connected to an oil replenishing part, and the oil replenishing part will splash the lubricating oil upward onto the vertical shaft and the bearing surface during the rotation of the transmission shaft.

[0006] Preferably, as an improvement, the oil replenishing member is a sleeve with external threads processed on the surface.

[0007] Preferably, as an improvement, the bushing is fixed at the middle of the transmission shaft.

[0008] Preferably, as an improvement, the shaft sleeve is bolted to the transmission shaft.

[0009] The principles and advantages of this solution are as follows: in actual application, when the disc separator is working, the transmission shaft rotates at high speed driven by the motor, and the sleeve on the transmission shaft rotates accordingly. During the rotation of the sleeve, the external thread rolls the lubricating oil in the transmission box upward, so that the lubricating oil can contact the vertical shaft and bearings above, and assist in lubricating the vertical shaft and bearings. The sleeve has the best auxiliary lubrication effect in the middle of the transmission shaft. The structure of the external thread is less resistant to the lubricating oil during the rotation of the transmission shaft, and will not affect the normal operation of the transmission shaft. The thread can push the lubricating oil better and throw it upward. In this way, compared with the prior art, the technical solution of the utility model can better lubricate the vertical shaft bearings, reduce the probability of wear between the shaft and the bearings, extend the life of the bearings, reduce the frequency of maintenance and replacement, and reduce labor and material costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following is further described in detail through specific implementation methods:

[0012] The reference numerals in the drawings of the specification include: transmission box 1, transmission shaft 2, shaft sleeve 3, worm wheel 4, worm 5, vertical shaft 6, bearing 7.

[0013] The embodiment is basically as shown in the attached Figure 1 As shown: a lubrication aid structure of a disc separator, including a transmission shaft 2 located in a transmission box 1 of the disc separator, the transmission box 1 is filled with lubricating oil, the transmission shaft 2 is keyed to a worm wheel 4 located in the transmission box 1, the bottom end of the vertical shaft 6 of the disc separator is coaxially connected to a worm 5, the worm 5 extends into the transmission box 1 and meshes with the worm wheel 4 for power transmission, the middle part of the transmission shaft 2 is bolted to a shaft sleeve 3, the shaft sleeve 3 is processed with an external thread, and during the rotation of the transmission shaft 2, the oil replenishing part throws the lubricating oil upward onto the surface of the vertical shaft 6 and the bearing 7.

[0014] The specific implementation process is as follows: When the disc separator is working, the transmission shaft 2 rotates at a high speed driven by the motor, and the sleeve 3 on the transmission shaft 2 rotates accordingly. During the rotation of the sleeve 3, the external thread rolls the lubricating oil in the transmission box 1 upward, so that the lubricating oil can contact the vertical shaft 6 and bearing 7 above, and assist in lubricating the vertical shaft 6 and bearing 7. The sleeve 3 has the best auxiliary lubrication effect in the middle of the transmission shaft 2. The structure of the external thread is less resistant to the lubricating oil during the rotation of the transmission shaft 2, and will not affect the normal operation of the transmission shaft 2. The thread can push the lubricating oil better and throw it upward. In this way, compared with the prior art, the technical solution of the utility model can better lubricate the vertical shaft 6 and bearing 7, reduce the probability of wear between the shaft and the bearing 7, extend the life of the bearing 7, and reduce labor and material costs.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
